This recipe tastes *nothing* like the restaurant recipe (RR). I have found several copycat (CC) recipes in the past for other dishes...so I am familiar with small changes or exceptions that occur b/c we may not have the exact details from the RR...but this was TERRIBLE! First...I am SURE the RR has garlic. Additionally, RR is BAKED with the cheese on top. There are no baking instructions on this CC. And adding WINE to dairy?? Only causes curdling. IMO, you're probably supposed to add the wine to the butter & shallots. This has virtually no flavor and reminded me of a plain bechamel with shrimp, artichokes, & spinach. I also think the artichokes used in the RR are soaked in something...They probably come packed in flavored brine or something similar. Not even a close facsimile.
I've made this twice now- making a few adjustments. I used green onions instead of shallots, because that was what I had on hand, and 1 cup of heavy whipping cream and 1 cup of milk. Instead of mozzarella, I used Parmesan, and at least 1 1/2 cups of that. It needed a bit of salt, but other than those changes it's a great recipe. I'll continue to tinker with it and it I'm sure it will become one of my go-to recipes.
